您能否告訴我，我做錯了什麼，該照片未顯示在新Instagram中？它根本沒有出口。Instagram iPhone掛鉤 - 未導出照片
編輯：我看到的問題是，它不顯示在Instagram的預覽。當我去「下一步」時，可以看到縮略圖。如果有問題，我的輸出圖片是1000x1000。
NSString *savePath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/Image.igo"];
// Write image to PNG
[UIImageJPEGRepresentation(preview.image, 1.0) writeToFile:savePath atomically:YES];
NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"];
if ([[UIApplication sharedApplication] canOpenURL:instagramURL])
{
//imageToUpload is a file path with .ig file extension
documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:savePath]];
documentInteractionController.UTI = @"com.instagram.exclusivegram";
documentInteractionController.delegate = self;
documentInteractionController.annotation = [NSDictionary dictionaryWithObject:@"bla bla bla" forKey:@"InstagramCaption"];
[documentInteractionController presentOpenInMenuFromRect:CGRectZero inView:self.view animated:YES];
